Solid state navigation device

摘要

A solid state navigation device comprises a solid state dielectric nub with an upper surface configured for being contacted by an object. The upper surface comprises an intervening dielectric layer. A plurality of conductor electrodes is disposed beneath at least a portion of the intervening dielectric layer. The plurality of conductor electrodes is configured to sense a change in capacitance coupling of the plurality of conductor electrodes to the object. The change in capacitance is caused by the object contacting and moving about the upper surface.
